Post construction noise level testing

Noise level measurements do not need to be taken at the post construction stage if the acoustician has accurately modelled the noise level from the plant, using manufacturer’s literature, and site measurements taken at the design stage. Any attenuation measures specified by the acoustician in their report must be confirmed as being present post construction.

If the acoustician has been unable to model the noise level accurately, post construction measurements are needed to demonstrate compliance.

Calculations and recommendations from the acoustician are relied on to be accurate and in keeping with best practice; attenuation measures are assumed to be specified and installed correctly.
